GQ8A036802DAT Description

The GQ8A036802DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 68K Ohm resistance value with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances versatility in various circuit designs.

GQ8A036802DAT Features

• Precision Performance: 0.5% tolerance and ±25ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case provides excellent thermal stability and mechanical durability.
• High Power Handling: 0.75W total power rating (0.1W per resistor) supports energy-intensive designs.
• Compact & Reliable: QSOP package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm height tolerance ensures consistent mounting.
• Isolated Design: Independent resistors (ISOL circuit designator) enable flexible circuit configurations.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 125°C.
